And as far as alternatives, in the Southbay it's very limited. I looked into this when I moved earlier this year and even Sonic only had DSL available where I live now. AT&T didn't even offer gigabit, and I'm not exactly in a bad spot other than that it's a suburb area (but I'm extremely close to a HQ for a FAANG).

Sonic fiber is available by building, not neighborhood.
In contrast, AT&T DSL FTTN (Fiber to the Node) and Sonic DSL (not resold) have been rock solid. I am using AT&T for both home and business now and can't remember the last time there was an outage or issues with the modem. For me, a stable connection at 50mbps is preferable to unstable 1gig.
I would rather support Sonic, but they don't have fiber in my area and I had a bad experience with their resold AT&T FTTN service that was beyond their control. Their straight DSL product is solid, as long as you are close to the central office and can get a good speed.
ISP monopolies are a huge problem and I find smaller ISPs tend to have better services. My previous apartment has a dedicated support team from a small ISP, and the tier 1 rep on the support line was capable of explaining the building's network topology and how they do natting.

My other options are DSL, so it's going to max out at 20Mbps or so.
I do have roof access, so I guess I could also see about MonkeyBrains.
All that said, during the outage, I just tethered to my iPhone on an AT&T unlimited plan, and was able to stream full quality video to my laptop. I think I speed tested it to about 80Mbps.
I suppose Sonic is also an option that I would love to entertain, but they're just reselling AT&T DSL here.
If only we had municipal broadband, but the corps own the infrastructure and have long contracts with the cities :(
